I agree with celica330, they just cost too much.In an aircraft game most ppl will buy an aircraft that die eaily doin stuff all on damage,also a flame tank for nod is a betta option. Snipers only do about 20 a clip vs a flame tank, and they only cost 800 with 400/400 health/armor, which means that aircraft really do nothing when it comes to kill time, and some sniper will just sit where they cant be hit and load off a clip, i beleive it is betta to buy something which is more effective and can take a decent hit. That is the reason why i agree with celcia330, the only reason ppl like aircraft is cause they can go up and down.
